[TYPO3-english] First problems. Sharing a MySql database

[Giuseppe Luigi]

Hi all,

I'm on the way of installing new 4.5 in my host.

The problem is, thath I only have 1 database, and I can't create more,
but Typo3 installation, only gives me the options, of choose an empty
database, or create one.

Skipping 1.2.3 wizard, I only see (about databases):
Database:
(Can only select database if username/password/host is correctly set
first) 

But this data is correctly entered.

Can't I use Typo3 in a shared database with other site, using prefixes
for each table?

Cheers.
